航空发动机滚动轴承工作在高温、高压、高转速的恶劣环境下,故障率高,因此对于其故障的准确识别和判断尤为重要。但由于轴承故障的偶发性,各类故障样本不均衡的问题非常突出,大大影响了基于数据的模式识别方法的准确性。本文提出了一种样本不均衡条件下的航空发动机滚动轴承智能诊断方法,采用合成少数类过采样方法进行样本平衡,在完成时频域特征提取和特征选择之后,利用改进蜂群算法优化后的随机森林策略实现轴承故障分类,并在凯斯西储大学轴承数据集和实验室构建的模拟航空发动机滚动轴承数据集上进行了实验验证。结果显示在凯斯西储大学中度不均衡数据集下,故障识别的准确率为98.30%,在重度不均衡数据集下的分类结果为96.30%。在实验室构建的模拟航空发动机滚动轴承实验台上,不均衡数据集的分类结果为97.65%,重度不均衡数据集的分类准确率为95.67%。相关实验证明本文所提算法能够有效完成不均衡样本下的航空发动机滚动轴承故障诊断任务。

The plastic deformation of the pipe made of Cu-based alloy hardened by incoherent nanoparticles and subjected to theuniform internal pressure was investig.ted. The limits of elastic and plastic resistance are determined. The insig.ificantexcess in the limit of the elastic resistance enables the plastic deformation in the most part of the pipe wall. The densities ofshear-forming.dislocations and prismatic dislocation loops are hig.er in alloys streng.hened with coarse particles than inalloys streng.hened with fine particles. At small distances between the streng.hening.particles, this effect is the mostpronounced.

Sorption recovery of palladium (II) from nitrate weak acidic model solutions and solutions of spent catalysts on some ion exchang.rs with different physical and chemical structure has been investig.ted. The palladium concentration in contacting.solutions was 5.0 ? 10-5 – 1.0 ? 10-3 mol/L at nitric acid and potassium nitrate con-centrations 0.01 and 1.0 mol/L, respectively. It was shown that anion exchang.rs AV-17-8 as well as Purolite S 985 and A 500 possess the best sorption and kinetic properties. These sorbents can be recommended for selective recovery of palladium from solutions of spent catalysts.

The restricted neurog.nesis limits the brain ability to overcome neuronal cell death following.ischemic lesion：Failure of the damag.d brain to reg.nerate following.cerebral ischemia results in functional deficits those are most often irreversible and can further deteriorate,causing.mortality and severe disability,prog.essive memory loss and cog.itive impairments,known as dementia.

The neuromodulatory transmitter serotonin(5-hydroxytryptamine,5-HT)is synthesized by neurons located in the brainstem,which project more or less densely to the entire central nervous system(Charnay and Leg.r,2010).Serotonin reg.lates a variety of physiolog.cal functions,including.food intake,reward,reproduction,sleep-wake cycle,memory,cog.ition,emotion,and mood(Charnay and Leg.r,2010).

Previously, we used heterolog.us expressed sequence tag.（EST） mapping.to g.nerate a profile of 4 935 pathog.n-response g.nes of Arabidopsis thaliana. In this work, we performed a computer analysis of this profile, revealing.1594 non-homolog.us clustered g.nes distributed among.all A. thafiana chromosomes, whose co-reg.lation may be related to host responses to pathog.ns. To supplement computer data, we arbitrarily selected two clusters and analyzed their expression levels in A. thaliana ecotypes Col-0 and C24 during.infection with the yellow strain of Cucumber mosaic virus CMV（Y）. Ecotype Col-0 is susceptible to CMV（Y）, whereas C24 contains the dominant resistance g.ne RCY1. Upon infection with CMV（Y）, all clustered g.nes were sig.ificantly activated in the resistant ecotype C24. In addition, we demonstrated that posttranslational histone modifications associated with trimethylation of histone H3 lysine 27 are most likely involved in reg.lation of several cluster g.nes described in this study. Overall, our experiments indicated that pathog.n-response g.nes in the g.nome of A. thaliana may be clustered and co-reg.lated.
